Add nodejs and npm to Jenkins docker image - node.js

Question

I'm trying to do a quick experiment or two with Jenkins. For this I intended to use the jenkins image and add nodejs and npm to it. Here's what I'm trying to do:
FROM jenkins
USER root
RUN curl -sL https://deb.nodesource.com/setup_6.x | bash - \
&& apt-get update \
&& apt-get install -y \
nodejs
RUN npm install -g npm
RUN npm --version
USER jenkins
The npm --version call will fail though, with this error:
Step 5/6 : RUN npm --version
---> Running in 48a250a4fdb8
module.js:471
throw err;
^
Error: Cannot find module 'process-nextick-args'

at Function.Module._load (module.js:438:3)
The command '/bin/sh -c npm --version' returned a non-zero code: 1
What is the proper way (if any) to fix this?

Answer 1

Try the following, it uses docker multi-stage build to copy dependencies from one image to another. This will allow you to avoid all the special things that need to be done to install node in docker. There is an official docker image that is built by the docker team, so you use that as follows:
FROM node
FROM jenkins
USER root
COPY --from=0 /usr/local /usr/local
RUN npm --version
USER jenkins
npm --version will output 5.3.0

Answer 2

Jenkins image by docker uses minimal installation for running Jenkins
FROM node:15.4 as nodejs
ENV JENKINS_HOME /var/jenkins_home
USER root
RUN rm -rf /var/lib/apt/lists/*
RUN rm -rf /etc/apt/sources.list.d/*
RUN apt-get update
#INSTALL NODE
COPY --from=nodejs /usr/local /usr/local
RUN node -v
RUN npm -v
